Obanai: I'll be dying soon as well, you won't be alone. Mitsuri: I don't want Iguro san to die… I wasn't able to be much of use, I'm sorry.
In my fear, I was suppressing my strength. But not anymore. Leave this to me. I will protect everyone.
I pray my impure blood is somehow cleansed. I want to be reborn into a peaceful world without demons. And then next time, I can tell you I love you. Obanai's internal dialogue to Mitsuri, Chapter 188.
Mitsuri is a master swordswoman who wields a pink Nichirin blade, a katana style blade made of scarlet ore and engraved with the words "destroyer of demons".
Both Obanai and Mitsuri give their all in this battle with their Flower Breathing and Serpent Breathing techniques to heavily contribute in killing the evil existence that was Muzan. But, as a result, they both also die, unable to spend any time with the one who they now realize they love.
Giyu Tomioka Fulfilled His Promise to Protect Tanjiro
The Water Hashira, Giyu, survived the "Infinity Castle" arc after fighting beside Tanjiro against Akaza and Muzan. Though his sword was snapped by Akaza, and he lost an arm to Muzan, Giyu fought with Tanjiro and his fellow Hashira with everything he had.
While a few people seem to like Muzan, even though it's difficult to understand the reason, this character doesn't have a single person that likes him. Having played a minor role in the Love Hashira's backstory in the latest episode, he can be recognized as the suitor who rejected Mitsuri's hand in marriage.
She calls Nezuko 'cute' and 'adorable' on multiple occasions. Also, Mitsuri seems to deeply respect Tanjiro for helping Nezuko stay alive and remarks that they have an adorable sibling bond.

Mitsuri's Sword Is Called the Pink Nichirin Sword

For Mitsuri, a main reason is that several fans believe that her sexuality is Bi or Pansexual because of her being titled as the Love Hashira. Though she's canonically in love with Obanai. People tend to believe that since Shinobu is next in line for one of her closest friends.
Despite her petite appearance, Mitsuri Kanroji has a special muscular composition that makes her muscles eight times denser than an ordinary human's. She is also more flexible than the other Hashira. These two strengths balance out her being the slowest runner out of all the Hashira.
Within this backstory came the origin of one of the demon slayer's most iconic pieces of clothing: the pinstripe green thigh-high socks she always wears. The item was a gift from her fellow Hashira, Obanai Iguro the Serpent Hashira, deeply implying that the latter has romantic feelings for Mitsuri.
The reason why her sword is like this is simply because it's the type of weapon that makes the most out of Mitsuri's Love Breathing Style, her unique muscle density, and her absurd flexibility.
Mitsuri's unique katana was said to be crafted by Tecchin Tecchikawahara, the chief of the Swordsmith village. Mitsuri is also the only known female Demon Slayer who was able to unlock the Demon Slayer mark, making her quite the powerful Hashira.
This Breathing Style is the personal creation of Mitsuri Kanroji, made by altering the Flame Breathing she learned from Kyojuro Rengoku to suit her special composition and physiology.
